Description

Technical Field

[0001] This utility model relates to the field of steel drum technology, specifically a high-strength steel drum based on a pre-coated plate. Background Technology

[0002] Steel drums are a traditional type of container and hold a very important position among traditional containers. They are widely used in industrial product packaging, transport packaging, and sales packaging. Currently, steel drums are mainly divided into two categories: closed-top steel drums and open-top steel drums. Closed-top steel drums are usually used for packaging liquid materials, while open-top steel drums are usually used for packaging solid materials.

[0003] However, traditional steel drums have many shortcomings in terms of manufacturing process and performance. On the one hand, traditional steel drums are mostly made of ordinary cold-rolled steel plates or hot-rolled steel plates. These steels themselves have limited strength and are prone to deformation or even breakage when subjected to greater pressure or external impact, affecting the service life of the steel drum and its ability to protect the contents. On the other hand, the anti-corrosion treatment of traditional steel drums is usually spraying or electroplating after forming. This post-processing method is not only complex and costly, but the adhesion between the coating and the steel is often not ideal. During long-term use, especially under harsh environmental conditions, the coating is prone to peeling off, leading to corrosion and rust. Therefore, it is necessary to design a high-strength steel drum based on pre-coated plates to solve the above problems. Utility Model Content

The drum body is rolled and welded from a high-strength pre-coated plate. The drum bottom and drum lid are both stamped from the high-strength pre-coated plate and welded to the drum body. The high-strength pre-coated plate is composed of a base steel plate, a hot-dip galvanized layer, a chemical conversion film layer, and an organic coating layer, which are sequentially composited. The outer wall of the drum body is provided with two sets of first reinforcing ribs in a ring shape, and the inner wall of the drum body is provided with multiple sets of second reinforcing ribs in a ring shape. The first reinforcing ribs and the second reinforcing ribs are staggered.

[0006] Preferably, the base steel plate is made of high-strength alloy steel, the hot-dip galvanized layer is formed on the surface of the base steel plate by a hot-dip galvanizing process to form a uniform and dense zinc layer, the chemical conversion film layer is formed on the surface of the galvanized layer by a chromate chemical treatment agent, and the organic coating is made of high-performance polyester resin coating.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-5 As shown, this utility model provides a high-strength steel drum based on a pre-coated plate, including a drum body 1, a drum bottom 2, and a drum lid 3. The drum body 1 is rolled and welded from a high-strength pre-coated plate. The drum bottom 2 and the drum lid 3 are both stamped from high-strength pre-coated plates and welded to the drum body 1. The high-strength pre-coated plate is composed of a base steel plate 4, a hot-dip galvanized layer 5, a chemical conversion film layer 6, and an organic coating layer 7 in sequence. The outer wall of the drum body 1 is provided with two sets of first reinforcing ribs 8 in a ring shape, and the inner wall of the drum body 1 is provided with multiple sets of second reinforcing ribs 9 in a ring shape. The first reinforcing ribs 8 and the second reinforcing ribs 9 are arranged alternately.

[0023] Specifically, a high-strength pre-coated plate can be formed by sequentially bonding a base steel plate 4, a hot-dip galvanized layer 5, a chemical conversion film layer 6, and an organic coating layer 7. The pre-coated plate can be rolled and welded into a barrel body 1 and stamped into a barrel bottom 2 and a barrel lid 3, giving the steel barrel high strength, corrosion resistance, and good surface properties. The staggered arrangement of the first reinforcing rib 8 and the second reinforcing rib 9 can enhance the overall strength and compressive strength of the steel barrel. Thus, through the above structure, high-strength steel barrels based on the pre-coated plate can be produced efficiently and reliably, ensuring the production efficiency of the steel barrel while greatly improving the overall strength of the steel barrel.

[0024] The base steel plate 4 is made of high-strength alloy steel. The hot-dip galvanized layer 5 is formed on the surface of the base steel plate 4 through a hot-dip galvanizing process, creating a uniform and dense zinc layer. The chemical conversion film layer 6 is formed on the surface of the galvanized layer using a chromate chemical treatment agent. The organic coating 7 is a high-performance polyester resin coating. The base steel plate 4, made of high-strength alloy steel, possesses excellent mechanical properties and tensile strength, providing basic support and load-bearing capacity for the steel drum. The zinc layer provides excellent corrosion resistance, preventing the base steel plate 4 from being directly exposed to the environment. The zinc layer is firmly bonded to the base steel plate 4, enhancing the material's durability. Chromate chemical treatment agent treats the surface of the galvanized layer to form a chemical conversion film layer 6, which can further improve corrosion resistance and enhance the adhesion between the galvanized layer and the subsequent organic coating layer 7. At the same time, the chemical conversion film layer 6 has self-healing ability and can delay the occurrence of corrosion. High-performance polyester resin coating is selected as the organic coating layer 7, which can provide additional corrosion resistance, weather resistance and wear resistance, improve the appearance quality of the steel drum, and give it a smooth and beautiful surface. Furthermore, through setting, a high-strength pre-coated plate can be formed, which is suitable for manufacturing high-performance steel drums, giving them the characteristics of high strength, corrosion resistance and strong weather resistance.

[0025] The bottom 2 and the lid 3 of the barrel are both provided with a flange structure 10. The flange structure 10 can increase the thickness and rigidity of the bottom 2 and the lid 3, so that they can better withstand external pressure and impact. When the steel barrel is subjected to external load, the flange structure 10 can disperse stress and reduce local deformation, thereby improving the overall strength and durability of the steel barrel.

[0026] The top of the barrel lid 3 is provided with a feed inlet 11 and an exhaust port 12. The top of the feed inlet 11 is threaded with a sealing cap 13, and the top of the exhaust port 12 is equipped with a one-way valve 14. The feed inlet 11 and the sealing cap 13 can be used for filling and sealing materials to ensure the airtightness of the steel barrel. The exhaust port 12 and the one-way valve 14 can be used to balance the internal pressure of the steel barrel and prevent the steel barrel from deforming or being damaged due to pressure changes.

[0027] The wall thickness of barrel body 1 is 0.8-1.2mm. The wall thickness of 0.8-1.2mm minimizes the amount of material used and reduces the overall weight of the steel barrel while meeting the strength requirements. The lighter weight makes the steel barrel more convenient to transport and handle, while reducing transportation costs. The reduction in material usage also reduces production costs and improves the economic efficiency of the steel barrel.

[0028] The barrel body 1 is equipped with handles 15 on both sides, which facilitates the handling, movement and operation of the steel barrel.

[0029] The surface of the barrel 1 is provided with a label pasting area 16 near the top. The label pasting area 16 allows for easy pasting of various product labels and markings, meeting the needs of product information display and traceability.

[0030] Working principle: First, a high-strength pre-coated plate is formed by sequentially bonding the base steel plate 4, hot-dip galvanized layer 5, chemical conversion film layer 6, and organic coating layer 7. The pre-coated plate can be rolled and welded into the barrel body 1 and stamped into the barrel bottom 2 and barrel lid 3, giving the steel barrel high strength, corrosion resistance, and good surface properties. The staggered arrangement of the first reinforcing rib 8 and the second reinforcing rib 9 can enhance the overall strength and compressive strength of the steel barrel. Thus, high-strength steel barrels based on the pre-coated plate can be produced efficiently and reliably, ensuring the production efficiency of the steel barrel while greatly improving the overall strength of the steel barrel, thereby completing the entire operation process.
